I figured it wouldnt be that big of a deal since it was a low mile truck (only 85k miles), and just thought it might be a dirty or bad injector or something.
I dropped it off at the local Ford Dealership my Uncle works at, and they called today saying that the turbo impeller is breaking apart and might be shooting shards of metal into the engine. Best case, they said I need a new turbo, and worst case, I need a whole new engine.
This seriously blows, as its a 12 year old truck, bought from a mom and pop place as-is, so Im not sure what to do. Has anyone else ever heard of this? Especially on a low mile truck? It figures that I buy the 7.3 because everyone says it is bulletproof, then it takes a crap on me a month after purchase.
Best case, what sort of turbo should I shoot for? Anything that will give good power/reliability in a daily driver without costing an assload of cash? Worst case, what should I do for the engine? Refurbished one? Crate engine? Im not sure what would be the best bet that wouldnt be that ridiculous in price, but still be a good engine to last for a long time in a daily driver setting.
Honestly, I would take the vehicle elsewhere to have it looked at. To me, that troubleshooting conclusion sounds dubious, at best. Whats breaking apart? The compressor wheel? I'd be amazed if it shot metal thru the intercooler and piping all the way to the intake plenums. The turbine wheel? The engine exhaust pressure would blow all that out the exhaust, not back into itself. Do yourself a favor and have it looked at elswhere. If the turbo is coming apart, a replacement isn't all that bad. Hell, with the symptoms you described, you could just have the CPS going bad.
